SPS 0 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 S3 S2 S1 S0
z SPS (Soft Power Saving, 2^nd standby mode): IC power saving, controlled by
software.
The operations are defined by the following table.

Soft power saving
If PS is at logic low level; the chip is forced to shut down all power. If PS is at logic high
level, the chip will be controlled by the SPS bit(the R15 bit of the register) to perform
normally(SPS=Low) or to softly power off the IC(SPS=High). It is recommended to keep PS
at low level (PS = L) while the chip is in no operation mode to save power for all
applications.
z D[9:0]: The level of sink current through pin SINK is set by D[9:0].
